Test whether nodes could be used on given filesystem where TMP

Skip teardown_dev if we have not created any devs yet.
and do not mkdir /dev/mapper dir when LVM_TEST_DEVDIR is set.
Drop this test from t-000-basic.sh.
It seems like test-suite is significantly slowed down on removal phase.
Maybe it should be part of generic teardown - though the reason of slowdown
should be also discovered - probably related to retry loop ?
When the srcdir == builddir we get the link on non-exectable file.
So make always sure fsadm.sh is executable script file.
Add cleanup target for lib/fsadm.
Currently test is skipped by default (since it needs code hack to work)
Check command line options to create & remove thin pools and thin volumes.
Activation code for thin LV support is missing, thus it only works without
driver loaded.
Some major distributions are still using 'mawk' and they are not using
the latest version - we end here with hidden dependency on the latest
version of mawk (1.3.4) while i.e. Debian Lenny seems to stay with 1.3.3.
So we end with completely broken vgimportclone script on such system.
We would need to check for proper support of :space: and abort build if
it doesn't work or simplier replace [:space:] with [ \t] which seems
sufficient to make it work (as can be seen in this patch)
A better fix would be to use command line parameter override - leaving
as FIXME comment.
This patch makes t-vgimportclone.sh test passing on Lenny.
daemon/common code in a single libdaemon.a, which is completely private. This
is currently linked into the lvmetad binary, and will be linked into LVM (the
client part, since static linking only picks up only symbols that are actually
used). I have also added --enable/disable-lvmetad to ./configure; although the
current default is off, I expect this to be flipped to on shortly. There's no
LVM-side support yet, but when there is, even when built, it'll still need to
be enabled by an lvm.conf option.
There is duplicate code in t-lvconvert-raid.sh and t-lvcreate-raid.sh.
This should be moved into a common file which is then sourced by these two
files. I'll wait to move the duplicate code until I can talk to mornfall.
Add config option to enable crc checking of VG structures.
Currently it's disabled by default.
For the internal test-suite this check it is enabled.
Note: In the case the internal error is detected, debug build with
compile option DEBUG_ENFORCE_POOL_LOCKING helps to catch the source
of the problem.

(Commited code has been different version of test).
So here it should be able to figure out new free name and create a new LV.
device that has been brought back from the dead: this sometimes fails with
clvmd (the cache is updated "too soon"). Instead, force a pvscan and rely on an
up-to-date cache as usual.
Since some test may leave devices in suspend mode which would require
carefull order of resume operation - use '-f' to replace them with
error targets
For disable_dev - when 'error' target is used for open count - treat
return code as ok (|| true) to avoid breaking futher test processing.
transient error), stemming from the following sequence of events:
1) devices fail IO, triggering repair
2) dmeventd starts fixing up the mirror
3) during the downconversion, a new metadata version is written
--> the devices come back online here
4) the mirror device suspend/resume is called to update DM tables
5) during the suspend/resume cycle, *pre*-commit metadata is read;
however, since the failed devices are now back online, we get back
inconsistent set of precommit metadata and the whole operation fails
The patch relaxes the check that fails in step 5 above, namely by ignoring
inconsistencies coming from PVs that are marked MISSING.
Patch adds check for stripe not only in direct
LV segment but also in mirror image segment.
This prevents bugs like:

# lvconvert -m1 -i1 vg_test/lv
# lvreduce -f -l1 vg_test/lv

This fails on lenny buildslave for some reason.
For now disable the vgimportclone part of the test until proper fix.
Let the first part of the test still run though, which shows pvs working
with duplicate pvs.

Fix use of released vgname and vgid
Avoid using of already released memory when duplicated MDA is found.
As get_pv_from_vg_by_id() may call lvmcache_label_scan() use the local copy
of the vgname and vgid on the stack as vginfo may dissapear and code was
then accessing garbage in memory.

Failure on pipe kills lv command and produces memory stacktrace.
Add 'true' for empty grep/sed to avoid generating stacktrace.
This should help with long time (7min) for this test on Lenny testing maching
(mimage was filler with stacktrace and each word was used as LV name).
This lvconvert is now able to complete operation automatically without question.
So remove 'echo y |' - it's breaking pipe on some bash versions.
i.e.:

./t-lvconvert-mirror-basic.sh: line 104: echo: write error: Broken pipe
while command has completed this operation succesfully
Currently the test are not properly working with new code.
Use settings for the previous behaviour.
FIXME: update tests to properly test new allocation policies.
Add a small fix that preserves pe_start for lvm1 PVs when being converted.
(this fix needs to be replaced with something more clever, but let's have this working now)
Add configurable option to define minimal size of
of block device usable as a PV.
pv_min_size() is added to lvm-globals and it's being
initialized through _process_config.
Macro PV_MIN_SIZE is unused and removed.
New define DEFAULT_PV_MIN_SIZE_KB is added to lvm-global
and unlike PV_MIN_SIZE it uses KB units.
Should help users with various slow devices attached to the system,
which cannot be easily filtered out (like FDD on /dev/sdX):

Instead of implicitly syncing udev operation in clustered and
file locking code - call synchronization directly in lock_vol() when
the operation unlocks VG
The problem is missing implicit fs_unlock() in the no_locking code.
This is used with --sysinit on read-only filesystem locking dir.
In this case vgchange -ay could exit before all udev nodes are properly
synchronised and may cause problems with accessing such node right after
vgchange --sysinint command is finished.
Add test case for vgchange --sysinit.
As the option 'set -e -o pipefail' is very sensite on pipe breaking
stop using '-q' for grep commands.
Otherwise this command (with large enough table) would fail:
dmsetup table | egrep -q
with exit code 141 (128 + SIGPIPE)
As Peter suggested, he prefers to keep '-o pipefail' - so make sure all
piped commands will read the whole output and will not exit too early.
